black white processing

--------------------------------
Black & White image processing is performed in three steps:

  1. You Get the image. This loads the image into the computer's memory.
  2. You Process the image. This may involve many different steps and menus.
  3. You Save the processed image to disk.

Since the image is in the computer's memory, you can hop from one processing menu to another without having to save the image between steps. For example, you might Stretch an image, apply a Median filter to smooth it, run a Gradient filter on it to enhance edges, then Save it to disk.

Remember, if you don't Save the image, and you leave the B&W Processing menu, the image just goes away and you have to start over. As long as you stay in the B&W Processing menu or any of its submenus, the image stays in the memory of the computer.
